A highway project is expected to cost $\backslash (\backslash$$ $1,300,000\backslash )$ initially. The annual operating and maintenance cost after the first year is $\backslash (\backslash$$ $5,000\backslash )$ and will increase by $\backslash (\backslash$$ $500\backslash )$ each year for a project lifespan of $20$ years. At the end of the tenth year, the project must be resurfaced at a cost of $\backslash (\backslash$$ $350,000\backslash ).$

$($a$)$ Calculate the present worth of costs $($in dollars$)$ for this project over a $20-$year period if the annual interest rate is $5$ percent. $\backslash$$

$($b$)$ Convert the value obtained in part $($a$)$ to equivalent uniform annual costs. $($Enter your answer in dollars as a positive value.$)\backslash (\backslash$$ $\backslash )$
